SPECIFICATION forming part of Letters Patent No. 652,735, dated J une26, 1900. Application filed. October 27, 1899. Serial No. 734,922. (Nomodel.)

To all whom t may concern.-

Be it known that I, ARTHUR EVERETT Sono- FIELD, a citizen of the UnitedStates, residing at Marblehead, in the county of Essex and State ofMassachusetts, have invented new and useful Improvements in Safety Snap-Hooks, of which thefollowing is a specifica= tion.

The object of this invention is to produce a safety snap hook, moreparticularly adapted for use in the rigging of a yacht, which shall bestrong and durable and which will not foul or catch upon any of therigging or sails of the yacht.

The invention consists in the combination and arrangement of parts setforth in the following specification and particularly pointed out in theclaims thereof.

Referring to the drawings, Figure 1 is a plan view of my improvedsnap-hook partly broken away and shown in section. Fig. 2 is atransverse section, line 2 2, Fig. 1. Fig. 3 is a side elevation of myimproved snaphook as particularly adapted for jibs. Fig. 4 is a section,line 4 4, Fig. 3. Fig. 5 is aside elevation of a jib-sheet and jib-staywith a series of jib snap-hooks similar to that illustrated in Fig. 3attached to the jib luft-rope.

Like numerals refer to like parts through!v out the several views of thedrawings.

In the drawings, 6 is a snap-hook for ordinary use in a yacht, in which7 is a ring to engage a rope, staple, or other fastening. 8 is a hookadapted to receive a stay 9. The opening 10, through which the stay 9 isintroduced into the hook 8, is normally closed by a pin 11. Said pin isfitted to slide in a hole 12, drilled in the body of the hook 6, and isbeveled at the end 13 to enter a V-shaped hole or socket 14. The end 13of the pin 11 is pressed into the socket 14 by aspiral spring 15 and isdrawn back by a cross -pin 16,

screwed into the pin 11, said pin projecting into the central aperture17 ofthe hook 6 and moving back and forward in a slot 18 in the 45 bodyof the hook. The slot 18 is at all times closed, so that nothing can getinto the hole 12, by a projection 19 upon the pin 11, so that when saidpin is in the position shown in Fig. 1 the projection 19 will close theslot 18.

In Fig. 3 I have illustrated a jib snap-hook similar to that shown inFig. 1, except that the eye 7 is replaced by a curved plate 20, groovedat 21 and fastened by seizings 22 to a jib lu-rope 23, (dotted lines.)

In Fig. 5 I have shown the jib snap-hook attached to a jib 24.

Having thus described my invention, what I claim, and desire by LettersPatent to secure, isv 1. In a snap-hook, an opening 10, a cylindricalsliding pin 11 arranged to slide in a cylindrical recess formed in thebody of the hook, a cross-pin fast to said sliding pin, a slot throughwhich said cross-pin projects, and aprojection upon said sliding pinadapted to slide in said recess and close said slot.

2. In a snap-hook, an opening 10, a spiral spring, a cylindrical slidingpin 11 arranged to slide in a cylindrical recess formed in the body ofthe hook, and normally held across said opening by said spring, across-pin fast to said sliding pin, a slot through which said cross-pinprojects, and a projection upon said sliding pin adapted to slide insaid recess and close said slot.

Iny testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

ARTHUR E. lSCHOFIELD.'
